'04 4Runner_U (L/O 0409) Rotating tires D Four- wheel drive models: Do not use tires of different brands, sizes, construction or tread patterns, as this may cause dangerous handling characteristics resulting in loss of control. Toyota recommends all four tires, or at least both of the front or rear tires be replaced at a time as a set. See "If you have a flat tire" on page 323 for tire change procedure. When a tire is replaced, the wheel should always be balanced. An unbalanced wheel may affect vehicle handling and tire life. Wheels can get out of balance with regular use and should therefore be balanced occasionally. When replacing a tubeless tire, the air valve should also be replaced with a new one. When rotating tires, check for uneven wear and damage. Abnormal wear is usually caused by incorrect tire pressure, improper wheel alignment, outof- balance wheels, or severe braking. To equalize the wear and help extend tire life, Toyota recommends that you rotate your tires according to the maintenance schedule. (For scheduled maintenance information, please refer to the "Scheduled Maintenance Guide" or "Owner's Manual Supplement".) However, the most appropriate timing for tire rotation may vary according to your driving habits and road surface conditions. See "If you have a flat tire" on page 323 in Section 4 for tire change procedure. 374 2004 4RUNNER from Sep. '04 Prod. (OM35847U)
